Decentralised Wastewater Treatment Systems

Overview
The decentralised wastewater treatment system is an approach which is a combination of the different systems such as the settler/ biogas settler, anaerobic baffled reactor, planted gravel filter (horizontal/ vertical) and polishing ponds. These systems are based on natural wastewater treatment techniques and are designed in accordance with different parameters such as the characteristics of wastewater, treated wastewater quality to be achieved, site and technical specifications. In these systems, both aerobic and anaerobic treatment process occurs. DWWT applications are based on four basic treatment modules:

Primary treatment includes pre treatment and sedimentation in settlers or septic tanks
